'What you might be looking at is an increase in passenger numbers,' Migdalia Travis, spokeswoman for the Customs and Border Protection (CBP) field office in Miami, told AOL Travel News. 'The amount of cruise passengers has increased and of course will account for an increase in contraband finds.'
Travis notes both Miami and Fort Lauderdale, the world's two largest cruise ports, have experienced a substantial increase in traffic, with more and bigger ships – Fort Lauderdale saw cruise traffic rise 17% in the last fiscal year to more than 3.3 million passengers."
